1. Create a "salt dough" by mixing ingredients in a large
bowl. Mix with your hands until the dough is smooth and firm. Add a
little bit more water to the mixture if needed.

2. Stand the clean soda bottle in the middle of the baking sheet.
Mold the salt dough around the bottle, making sure that you don't
cover up the bottle mouth (the hole at the top) or drop any dough
into the bottle. Take your time and build the volcano of your
dreams

3. Fill the bottle most of the way with warm water mixed with a
little of the red food colouring.

4. Add liquid dish detergent into the bottle.

5. Add baking soda to the water/detergent mixture in the bottle.

6. Slowly pour vinegar into the bottle and jump back!

Notice the red "lava" that flows out of your volcano. This happens
because of the baking soda and vinegar mixture. By mixing the two
together you produce a chemical reaction in which carbon dioxide gas
is created - the same gas that bubbles in a real volcano! The gas
bubbles build up in the bottle, forcing the liquid "lava" mixture out
of the bottle and down the sides of your volcano.
